HEEL-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,055, dated January 29, 1889.

Application filed June 8,1888. serial No. 276,427. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. lIELMs, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented new and useful Improvements in Ileel-Trinnning Machines, of which the following is a specificatitm.

This invention relates to a machine by which the heels of boots and shoes can be accurately trimmed, as set forth in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a heel-trimming machine. Fig. 2 is a section in the plane 00 m, Fig. 1. Fig. 3 is a section along the line y y, Fig. 2. Fig. 4 is a section along the line .2 ,2, Fig. 2. Fig. 5 is a detail side elevation of tools for working on the heel and rand, said Fig. being on a larger scale than the preceding figures.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a base or supporting frame. A movable frame,

B, is pressed by the spring 0 in the direction of arrow 1, Fi 2, and a link or rod, D, 0011- nected to a le\ er, E, can be made to move the frame I) in the direction opposed to arrow 1. The fulcrum of lover E is shown at F. The frame B has a spring, G, Fig. 2,which presses a pivot, ll, toward the pivot I. The screw thread of pivot I and the wheel K can be made to force said pivot I in the direction of arrow 3that is, toward the pivot II. The pivots II I can be made to clamp a shoe, L, and shoe-support M.

The shoe L contains a last with which the pivot I engages, and the approach of the pivots H I will press the shoe against the support M, and will cause said support M to be engaged by the pivot ll, so that the shoesupport is universally jointed to said pivot. The support M has a movable or sliding toeclamp, N, traveling on a guide, 0, and a heelrest, P, and pin or peg Q on the support M engaging the heel of the shoe L. \Vhen the toe-clamp N is slid into engagement with the toe of the shoe L, as seen in Fig. 2, the shoe is held firmly in place on the support M, the heel-rest P and peg Q engaging the heel of the shoe, as shown.

The pivot I is capable of being moved in the direction of the length of the shoe, as indicated by the arrow 2, Fig. 2, on the arm R, which supports the pivot I. A spring, S, tends to move the arm R in the direction opposed to said arrow 2. The motion of the arm R in the direction of arrow 2 will swing the shoe-support M and the shoe L in the direction of the arrow 2, shown on said shoe and on the shoe-heel, as will be hereinafter referred to. The lever 'l, swinging about the fulcrum U, Fig. l, can be made to move the arm R in the direction of the arrow 2 on said arm R. Said arm R can be made to swivel. or turn about its longitudinal axis by means of a handle, V. By swiveling the arm R and handle V in the direction of arrow 5, Fig i, the shoe L will be swung in the direction of the arrow there shown. By swinging or swiveling the handle V in the oppcste direction the arm R and shoe L will also be swung into the directions opposed to those. indicated by the arrows -t and A driving-pulley, Y, is adapted to connect by a belt (not shown) with a pulley, Z, and to rotate said pulley Z with its shaft 1) and with the tools or trimmer a c, secured to said shaft 1). The tool a. is made to act on the heel of the shoe L, and the tool 0 is made to act on the rand of the shoe. By swinging the shoesupport M and shoe L about the pivots II I different portions of the heel and rand can be presented to the tools a 0. By swinging the shoe L in the direction of arrow 2, Fig. 2, or in the direction of arrow 4, Fig. 4, the tools a c are made to act on the heel and rand at different angles. The desired amount and style of trimming can thus be rapidly accomplished.

A heel-guide, d, and rand-guide e prevent the frame 13 from carrying the shoe-frame M and shoe L too close to the tools (I, r, so that excessive trinnning or working is avoided. The spring X, Fig. 2, keeps the arm R in position to hold the pivot I in line with the pivot H when the handle V is released. Said spring X is connected with the swivel-frame \V and is braced against lugs or arms 2', rising from the frame 13. In the way or slot f, Fig. 2, of the swivel-frame slides the box 7L, which is tapped to receive the screw-thread of the pivot I. Said box 71 has flanges g, which guide said box 71 along the slot j". Said box 71 is caused to slide back and forth along the slot f by means of the spring S and lever T, as already deseribed, said lever 'l being eonneeted to the arm H, \vhieh arm R is seeured to the box 71 The lever T, as seen in Fig. i], is tulerumed on an arm, 7, whieh iseonneeted to thehandleY, so that said arm 7 will swivel as the frame \Y swivels. The handle Y is shown seeured to the frame by means of screws It.

What I eiaim as new, and desire to seeure by Letters Patent, is

1. The eombination ot' the reeiproeating' slide-frame l having a lengtlnvise-yielding projeeting pivot, ll, the shoe-su 'iport M, earrying a t'oe-elamp, N, and jointed to and supported by the projeeting end of the pivot, the vertieally-adjustable box 71, and the lengthwise-adjustablepivotl,extending-throng-lithe box and at ljust'able vertieally therewith tor pivotally (uie'aging' the last in the shoe and swinging the shoe-sumiort baek and t'orth to and from the slide-frame, substantially as deseribed.

2. The eombination ot' the reeiproeating slide-frame 13, having a tenethwise-movable projeeting pivot, ill, a spring, (i, for throwingthe pivot outward, a slme-sup mrt, M, earryin a toe'elamp, N, and jointed to and supported by the projecting: end of. the movable pivot, a vertieally-adjust'ai le box, 71, and a lengthwise-adjustable pivot, 1, extending through the box for pivotaltv engaging the last in the shoe, substantially as d( seribed.

3. The eotubiuation ot. the reeiproeating slidetrame .ll, having a piojeeting pivot, ll, the shoe-sup nn-t having; a toe-elam N, and universally jointed to the proietding end ot the pivot, the laterallyswing'ine' J'raIne \V, swiveled to the slide-frame and provided with a handle, V, a box, 7t, vertically adjustable on the swiveled frame, and a lengthwise-adjustable pivot, 1', extending through the box. and vertically adjustable therewith for pivotally engaging the last in the shoe and swinging the support to and from the slide-frame, substantially as d eseribed.

4-. The eombination of the reciprocating slide-t'rame 1;, having a lengtlvise-movable l'irojeetiug pivot, ll, a spring, G, for throwing the pivot outward, a shoe-support, 1\I,having a toe-(damp, N, and universally jointed to the projeeting' end of the movable pivot, the laterallyswinging i'rame \V, swiveled to the slide-Frame and having a handle, V, and slot .7; a spring-ilnpelled lengthwise-movable arm,

it, loeated in the swiveled t'rame,a box, 71, seeured to the arm in the slot of the swiveled frame, and a lengthwise-movable pivot, 1, extending through the box t'or pivotally engaging: the last in the shoe, substantially as deseribed.

5. The eombination ot' the reeiproeatiue slide-tranle .13, having a projeetiue' pivot, II, the shoe-support: M, jointed to the projecting end of the pivot, a laterally-swiaging frame, \V, swiveled to the slide-frame and provided with a handle, V, and a box, 71, a lengthwiseadjustable pivot, I, extending through the box for pivot'ally engagi ng' the last in the Shoe, and a spring, X seeu red to the swivel ed :tram e, for normally holding the latter and keeping the two pivots in line, substantially as deseribed.

In. witness whereotf I have hereunto set my hand and sea] in the presenee of two snbserib- 'ing witnesses.
